My membrane has a rubber o ring on both sides will this still work which side should I put the intake

This particular Filmtex SW30 2540 membrane has one rubber o-ring at one end. This o- ring has to go on the upstream side of its housing unit.

Does it work in idromar mini compact?

Yes, this membrane should work. If you check page 4 of your product manual, you will see it listed under replacement parts. That is this model.

What is the gph rating? what is the pressure required for this membrane? does it need a casing?

stone age needs to go DOW form 609-00377-0811available on website which provides the information requested. (Gph is gallons per hour) the form referenced previously indicates 700 gallon per day at 800 psig at 77 degrees F. A correctly designed casing is required. regards da vinci
